TVS-Diodes are widely used to protect electronic systems from damage due to transient voltage surges. The MAPLAD18KP48A is an integrated transient voltage surge suppression (TVS) device designed specifically for use in automotive applications. It provides reliable and cost-effective protection against surges up to transient peak pulse current of 8 kA while maintaining safe power operation. The device features unmatched off-state EMI providing Class B emissions.The MAPLAD18KP48A has a single-chip construction, consisting of a MOSFET gate driver, a power MOSFET, inductor, and a low capacitance diode. The MOSFET gate driver provides the needed voltage to drive the power MOSFET. The power MOSFET provides robust protection for the system, while at the same time providing a low-leakage current in the off state and high switching speed in the on state. The low capacitance diode provides fast voltage clamping to protect the unprotected side of the MOSFET while the inductor provides additional supply side protection.The MAPLAD18KP48A can be used in many different applications. It is ideal for automotive applications such as central locking systems, electric windows, ignition systems, ECU systems and vehicle communication systems. It is also suitable for consumer applications like home alarm systems and other consumer electronics. In addition, the device is suitable for professional applications such as computer systems and telecom systems.The MAPLAD18KP48A operates in two basic modes: dynamic and static. In the dynamic mode, the device is activated when a surge in the supply voltage is detected. The device clamps the voltage to a safe level to protect the device and surrounding components from damage. In the static mode, the device is in its off state. This preserves the system from emissions and power usage, while still allowing the system to be protected from transient voltage surges.The MAPLAD18KP48A is designed with a unique off-state EMI solution, providing Class B emissions. This ensures that the device is compliant with global standards for automotive and industrial applications. The device is very reliable and offers a low cost solution for protecting sensitive electronic systems.In summary, the MAPLAD18KP48A is an integrated transient voltage surge suppression device designed specifically for automotive applications. It provides reliable and cost-effective protection against transient voltage surges up to 8 kA. The device features unmatched off-state EMI providing Class B emissions and operates in two basic modes - dynamic and static. The device is very reliable and offers a low cost solution for protecting sensitive electronic systems.
